Abstract: ABSTRACT OF THE DISCLOSURE            A folding table having a top formed by a pair of hingedly connected sections, the adjacent edges of which approach one another as the table is unfolded and its top sections are brought into coplanar orientation, is equipped with a latch that is mounted at the underside of the top sections and comprises complementary interengageable relatively movable elements which, upon interengagement, hold the table top sections against unintended displacement from coplanar orientation.  One of the latch elements is biased to a position in which an edge thereof lies in the path of the other latch element during relative movement of the latch elements towards interengagement, and thereby blocks movement of the approaching edges of the table top sections beyond a point at which the space therebetween is wide enough to avoid pinching one's fingers.  A handle operatively connected with the biased latch element and movably mounted at the underside of one of the table top sections, enables the biased latch element to be moved out of its blocking position, the handle being located far enough from the adjacent edges of the table top sections to prevent any part of the hand used to activate the handle being pinched between said approaching table top edges.

Abstract: Abstract of the Disclosure The invention provides a new air ring for use with a die in a blown film process line to apply cooling air to the exterior surface of an extruded tube of film-forming material passing through the air ring.  Air is discharged from a first downstream gap in the air ring radially outward from the path of movement of a tube in unexpanded state so as to create a vacuum force that urges the tube outward and causes the cooling air to flow along the surface, permitting the use of much higher velocities than hitherto, the increased cooling permitting increased output for a given size of die.          A second upstream gap delivers a tubular stream that pre-cools the tube and prevents it from sticking to the structure between the upstream and downstream gaps.  A presently pre-ferred structure consists of a deflector ring spaced from the remainder of the air ring body to form the second upstream gap and having the air from the upstream gap flowing over its inner surface, and an axially movable control ring surrounding the deflector ring, the downstream gap being formed between the deflector and control rings and adjustable in size by axial movement of the control ring.

Abstract: ALKYL PHENOL ETHER OF POLYETHYLENE GLYCOL AS STABILIZER OF AIR FRESHENER            Abstract of the Disclosure Compositions of fragrance oils are stabilized with respect to potency and aesthetic quality toward the effects of heat and age by including in the formulations a quantity of alkylphenol ethers of polyethylene glycol, or more specifically, alkyl phenoxy polyethoxy ethanols wherein the polyether chain averages from 5 to 13 moles of ethylene oxide, and the alkyl portion of the molecule ranges from 6 to 20 carbon atoms.  The alkyl portion of the molecule may be branched, unbranched, saturated or unsaturated.  The oils are stabilized in respect to durability or intensity of odor with time and are rendered relatively insensitive to the deleter-ious effects of heating and/or aging in the presence of air.          The presence of the stabilizers also eliminates the phenomenon of the "migration" of the perfume oil caused by repeated vaporization and condensation within an enclosed space.  In addition, the inclusion of the stated stabilizers, when judiciously used, tends to "round out" or "smooth out" the overall perception of the odor characteristics of the particular oils utilized, often increasing the aesthetic value of the fragrance composition when so used.

Abstract: ABSTRACT       Process for drilling a hole in the earth's crust in which the bottom of the drill hole is frozen in front of or near the drill bit by a cold drilling liquid in which liquid particles that have been frozen to solid parts or have been solidified have been taken up whether or not by addition.  In this way the bottom of the drill hole is always so hard - also upon drilling in soft or plastic formations, such as clays, - that use can be made of diamond drill bits or other drill bits normally used for hard formations, in order that the number of times a drill bit is to be replaced can be strongly reduced.  The purpose of adding ice is to make it possible for a sufficient amount of frigories per unit of time to be introduced into the drill hole, so that at greater depths the temperatures at the drill bit are decreased to such a degree that here, too, use can be made of drill bits for hard formations here described.         By preference, the drilling liquid is a mud consisting of an eutectic salt water solution with plastering properties, to which ice of the same composition has been added.         The pressure in the drilling liquid in the bottom of the drill hole is somewhat lower than the pressure of the liquid in the drilled formation, so that during the drilling the drilling liquid cannot penetrate into the layer, but a slight influx of water from permeable rocks can take place, as a result of which all drilled layers, both permeable and non-permeable ones, will be frozen.  The lower pressure on the bottom of the drill hole is achieved by injecting a gas, in the circulating drilling liquid to reduce its (mass) density.  Regulation of the pressure in question may take place with the aid of a throttling element which controls the over-pressure required at the top of the annular circuit between the drilling string and the drill hole wall.         The invention further relates to an installation for realizing the process according to the invention.  This installation is mainly characterized by means included in the drilling liquid system at the ground level to cool drilling liquid and change it partly to ice, by means to add a gas to the drilling liquid, and by means to control the over-pressure at the top of the annular circuit between the drilling string and the drill hole wall.         The process according to the invention may be applied in any production process for recovering energy, such as production of oil or natural gas, thermal energy and thermal energy from coal formations and oil shales or oil sands.

Abstract: TITLE OF THE INVENTION              STRAIGHT HOLE FORMATION WITH MOVING GUIDE             PATH              ABSTRACT OF THE DISCLOSURE           In winding coils of great wall thickness such coils including a plurality of layers each formed of a plurality of figure-8s with the cross-overs progressing angularly around in each layer and with a radial hole extending from the outside of the coil into the axial opening thereof, by previous winding methods it is likely that the hole will be curved, even in cases where the guide for traversing the flexible material on the mandrel is spaced away from the mandrel and the outside of the wound material.  In order to prevent the formation of a curved hole and to ensure that the hole is substantially radial, the guide carrier is moved in such a way that the line from the carrier to the surface of the coil always remains substantially tangential to the package at the same angular position in space with respect to the mandrel.

Abstract: "FORCED AIR HEATER BLOWER"                       ABSTRACT OF THE DISCLOSURE           This invention relates to a skid-mounted portable heater blower unit for use on the surface to supply high temperature hot air to subsurface installations for the purpose of shrinking heat shrinkable sleeves around splices or other repairs made in underground cable, such heater being characterized by a serially-ducted preheater which draws ambient air in from the outside and warms it by passing it through the ducts back and forth four times in heat exchange relation to the hot products of combustion exiting  the unit along the outside of an internal combination combustion chamber and final stage heat exchanger.  The preheated air from the final pass through the preheater enters the secondary stage heat exchanger and follows a helical path around the outside of the combustion chamber while flowing in concurrent relation to the flame inside thereof and countercurrently to the products of combustion exiting  around the outside.  The air thus heated is preferably given one last charge of heat by passing it in heat exchange relation to the hot gaseous products of combustion just as they leave the combustion chamber and begin their migration along the outside of the secondary stage heat exchanger.
